CUSCUTA AUSTRALIS AU BURKINA FASO : POTENTIELS HOTES ET DUREE DE SON CYCLE BIOLOGIQUE EN CONDITIONS DE SERRE.
Journal Title: International Journal of Advanced Research (IJAR) - Year 2018, Vol 6, Issue 11
Abstract
Le genre Cuscuta de la famille des Convolvulaceae comporte environ 150 esp?ces herbac?es liano?des commun?ment appel?es cuscutes et infestent les plantes tant sauvages que cultiv?es. Cuscuta australis R. Br. est la seule cuscute existant au Burkina Faso. L?objectif principal de cette ?tude est d?identifier les principaux facteurs qui interviennent dans l?accomplissement du cycle biologique de Cuscuta australis. Un inventaire des esp?ces v?g?tales h?tes de la cuscute dans des parcelles cultiv?es dans la ville de Ouagadougou et une culture de la plante parasite en conditions de serre ont ?t? r?alis?s. L?inventaire a permis de d?nombrer 43 plantes h?tes dont 16 esp?ces cultiv?es et 27 esp?ces sauvages. Ces plantes rel?vent de 37 genres et de 21 familles. Les plantes de Cuscuta australis cultiv?es seules en conditions de serre sont mortes au bout de 31 jours apr?s semis (JAS). Cependant, en pr?sence d?une plante h?te, la plantule de la cuscute a ?tabli un contact parasitaire 13 JAS, suivi de d?g?n?rescence de la racine et la formation de l?haustorium. La floraison et la fructification sont intervenues respectivement 65 et 77 JAS. Cette ?tude permet de conclure que Cuscuta australis, parasite obligatoire et polyphage serait r?pandue au Burkina Faso. Des ?tudes pour d?terminer la distribution g?ographique du parasite sur l?ensemble du territoire burkinab? ainsi que l??valuation des pertes de rendements agricoles caus?es par cette esp?ce et la recherche de m?thodes de lutte sont n?cessaires.
